Abstract: A support frame for metal coils, which are stacked on top of each other for a heat treatment by means of a hot, gaseous medium, especially in bell-type annealing furnaces, has devices on the support frame for guiding the flow of the medium through the coils. The support frame is a framework constructed of I-sections. The end surfaces of the coils are supported on the flanges of the framework I-sections. The webs of the framework I-sections are provided with holes, which serve for guiding the flow of medium.

Abstract: A good heat treatment of metal coils (31, 32) is obtained by means of gaseous hot media, whereby said metal coils are successively wound with support frames (10) between them. According to the invention, a low-cost robust support frame (10) may be obtained, whereby an I-profile is used as frame profile (28), so construct a frame, which then forms the support frame (10). The I-profile web has rows of holes (24), to serve as a guide for the medium.

Abstract: Apparatus for bending sheets of glass by means of a bending press comprising a convex bending mold provided with a bending surface and an opposed concave bending molding, the surfaces of the bending molds in contact with the window being heated to a temperature approximating the bending temperature of the sheet of glass, wherein the concave bending mold consists of a frame which is only in contact with the sheet of glass at its periphery and wherein heaters are mounted within the frame for heating the bending surface of the convex bending surface of the opposed convex mold.
